Wings span cast black upon vigils

Aesop believes that capitalism and the desire for material goods has overshadowed religious holidays. A vigil is the day before a religious feast observed as a day of spiritual preparation. This is being blacked out by the shadow created by commercialism (represented by wings). Wings in this song have been used multiple times as metaphors for commercialism and success.

These wings could also be an allusion to the video game Duck Hunt, which Aesop appears to be using as a metaphor for our capitalistic/materialistic society. The best example of this is Christmas, which is a religious holiday that has slowly evolved into more of a commercial holiday.
